# Firmware 3.1.0 Upgrade Guide

To ensure the stability and security of your KeyPal 2 device, we recommend upgrading your device to the latest firmware version in a timely manner. Before upgrading, please make sure your recovery phrase has been properly backed up. During the entire upgrade process, keep the device connected to your computer and avoid disconnecting it or closing the browser page.

### Before You Start

Before upgrading, please prepare your KeyPal 2 device, a USB cable, and a computer. We recommend using **Google Chrome** or **Firefox** for the upgrade.

Open the KeyPal firmware upgrade page in your computer browser:

[**https://connect.keypal.pro/**](https://connect.keypal.pro/)

During the upgrade process, please make sure the USB connection is stable. Do not disconnect the device, close the browser, or refresh the upgrade page.

### Step 1: Connect the Device and Open the Upgrade Page

First, turn on your KeyPal 2 device and connect it to your computer using a USB cable.

After the device is connected, open the upgrade URL in **Google Chrome** or **Firefox** on your computer:

[**https://connect.keypal.pro/**](https://connect.keypal.pro/)

After entering the upgrade page, the system will automatically recognize the device and check the current firmware version.

### Step 2: Check the Firmware Version

Once the device is detected on the computer, the current firmware version will be displayed.

If a new firmware version is available, click **“Update Available”** on the page to enter the firmware upgrade process.

Next, the system will guide the device into **Bootloader mode**. Please follow the prompts on both the computer and the device to continue.

### Step 3: Confirm Safety Before Upgrading

Before the official upgrade begins, the system will display a security reminder.

Please make sure you have properly backed up the recovery phrase of your KeyPal 2. The recovery phrase is the only important credential for restoring your wallet assets. Do not take screenshots, photos, or share it with anyone.

After confirming that your recovery phrase has been backed up, check the confirmation box on the computer and click **“Continue”**.

If you have not backed up your recovery phrase, please stop the upgrade first and continue only after completing the backup.

### Step 4: Enter Bootloader Mode

According to the page instructions, please confirm the upgrade command on your KeyPal 2 device.

After confirmation, the device will restart and enter **Bootloader mode**. Once in this mode, the device will begin receiving the files required for the upgrade.

During the upgrade process, the device screen may display progress for receiving resource files, firmware files, Bluetooth update packages, and other required files. Please follow the device screen prompts and wait until the receiving process is complete.

### Step 5: Device Ready

After the device finishes receiving the upgrade files, the computer page will show that the device is ready.

At this point, click **“Install Firmware”** on the computer to begin installing the new firmware.

Before clicking install, please confirm again that the device is still properly connected to the computer via USB cable.

During this process, keep your KeyPal 2 connected to the computer and do not disconnect the USB cable.

Do not disconnect the USB cable;\
Do not close the browser;\
Do not refresh the page;\
Do not shut down the computer;\
Do not force restart the device.

Disconnecting during the process may cause the upgrade to fail. Please wait until the system indicates that the upgrade is complete.
